This will manage variables in the default .env.example file in the current directory.

File Options

The tool provides flexibility in choosing which environment file to manage:

# Default usage (manages 'env-prod' in current directory)
./env_manager.py

# Using -f or --file to specify a different file
./env_manager.py -f .env.production
./env_manager.py --file /path/to/your/.env

# Examples
./env_manager.py -f .env.staging     # Manage staging environment
./env_manager.py -f .env.local       # Manage local environment
./env_manager.py -f configs/.env     # Manage env file in different directory

If the specified file doesn't exist, the tool will create it automatically when you add your first variable.
